Specimens with relative density above 96% were produced after sintering. Structural and phase composition studies revealed predominant monoclinic Fergusonite structure for the majority of samples. SEM and TEM studies elucidated the effect of the used dopant combinations on grain growth, micro-crack formation and secondary phase formation. Results from microstructural study were correlated to the grain interior and grain boundary conductivities for selected samples (La0.99Sr0.01Nb0.99Al0.01O4−δ and La0.99Sr0.01Nb0.99Ti0.01O4−δ). The majority of co-doped niobates exhibited appreciable protonic conductivity under humid atmospheres at intermediate temperatures. Sr- or Ca-doped compounds displayed the highest total conductivities with values for LSNA equal to 6 × 10−4 S/cm and 3 × 10−4 S/cm in wet air and in wet 4% H2–Ar (900 °C), respectively. Additionally, thermal expansion was studied to complete functional characterization of co-doped LaNbO4. 000255478 536__ $$0G:(DE-HGF)POF3-113$$a113 - Methods and Concepts for Material Development (POF3-113)$$cPOF3-113$$fPOF III$$x0 000255478 588__ $$aDataset connected to CrossRef 000255478 7001_ $$0P:(DE-Juel1)129637$$aMeulenberg, Wilhelm A.$$b1$$ufzj 000255478 7001_ $$0P:(DE-HGF)0$$aPalisaitis, Justinas$$b2 000255478 7001_ $$0P:(DE-Juel1)129662$$aSebold, Doris$$b3$$ufzj 000255478 7001_ $$0P:(DE-HGF)0$$aSolís, Cecilia$$b4 000255478 7001_ $$0P:(DE-Juel1)129815$$aZiegner, Mirko$$b5$$ufzj 000255478 7001_ $$0P:(DE-HGF)0$$aSerra, Jose M.$$b6 000255478 7001_ $$0P:(DE-Juel1)130824$$aMayer, Joachim$$b7$$ufzj 000255478 7001_ $$0P:(DE-Juel1)129729$$aHänsel, Michael$$b8$$ufzj 000255478 7001_ $$0P:(DE-Juel1)161591$$aGuillon, Olivier$$b9 000255478 773__ $$0PERI:(DE-600)2013983-4$$a10.1016/j.jeurceramsoc.2014.11.009$$gVol. 35, no. 4, p. 1239 - 1253$$n4$$p1239 - 1253$$tJournal of the European Ceramic Society$$v35$$x0955-2219$$y2015 000255478 8564_ $$uhttps://juser.fz-juelich.de/record/255478/files/1-s2.0-S0955221914006128-main.pdf$$yRestricted 000255478 8564_ $$uhttps://juser.fz-juelich.de/record/255478/files/1-s2.0-S0955221914006128-main.gif?subformat=icon$$xicon$$yRestricted 000255478 8564_ $$uhttps://juser.fz-juelich.de/record/255478/files/1-s2.0-S0955221914006128-main.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000255478 8564_ $$uhttps://juser.fz-juelich.de/record/255478/files/1-s2.0-S0955221914006128-main.jpg?subformat=icon-180$$xicon-180$$yRestricted 000255478 8564_ $$uhttps://juser.fz-juelich.de/record/255478/files/1-s2.0-S0955221914006128-main.jpg?subformat=icon-640$$xicon-640$$yRestricted 000255478 8564_ $$uhttps://juser.fz-juelich.de/record/255478/files/1-s2.0-S0955221914006128-main.pdf?subformat=pdfa$$xpdfa$$yRestricted 000255478 8767_ $$92014-12-31$$d2015-01-26$$eColour charges$$jZahlung erfolgt 000255478 909CO $$ooai:juser.fz-juelich.de:255478$$popenCost$$pOpenAPC$$pVDB 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129617$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129637$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129662$$aForschungszentrum Jülich GmbH$$b3$$kFZJ 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129815$$aForschungszentrum Jülich GmbH$$b5$$kFZJ 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130824$$aForschungszentrum Jülich GmbH$$b7$$kFZJ 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129729$$aForschungszentrum Jülich GmbH$$b8$$kFZJ 000255478 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)161591$$aForschungszentrum Jülich GmbH$$b9$$kFZJ 000255478 9131_ $$0G:(DE-HGF)POF3-113$$1G:(DE-HGF)POF3-110$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lEnergieeffizienz, Materialien und Ressourcen$$vMethods and Concepts for Material Development$$x0 000255478 9141_ $$y2015 000255478 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ EUR CERAM SOC : 2014 000255478 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000255478 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000255478 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000255478 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000255478 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000255478 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000255478 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000255478 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000255478 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000255478 920__ $$lyes 000255478 9201_ $$0I:(DE-Juel1)IEK-1-20101013$$kIEK-1$$lWerkstoffsynthese und Herstellungsverfahren$$x0 000255478 9201_ $$0I:(DE-82)080011_20140620$$kJARA-ENERGY$$lJARA-ENERGY$$x1 000255478 980__ $$ajournal 000255478 980__ $$aVDB 000255478 980__ $$aI:(DE-Juel1)IEK-1-20101013 000255478 980__ $$aI:(DE-82)080011_20140620 000255478 980__ $$aUNRESTRICTED 000255478 980__ $$aAPC 000255478 981__ $$aI:(DE-Juel1)IMD-2-20101013
